    Abstract: A fluid filtration assembly includes a filter housing having a first end for fluid connection with a fluid storage vessel. A filter cartridge is disposable within the filter housing, and a plunger pump is coupled at a second end of the filter housing. The plunger pump includes a housing having a rigid portion and a flexible portion. The flexible portion has a plunger-engaging portion for coupling to the plunger of an actuator. The flexible portion selectively movable with respect to the rigid portion via the actuator. The filter cartridge can be a hollow fiber filter. The plunger pump can be configured to induce alternating tangential flow in at least a portion of the assembly. The fluid filtration assembly can be provided as a disposable single-use arrangement.

    Abstract: A control unit includes a first connector configured to connect a proportional pressure regulator to a positive pressure supply and a second connector configured to connect the proportional pressure regulator to a negative pressure supply. The control unit further includes at least one sensor configured to detect an amount of air flow (volume per unit of time), positive or negative, within an air flow line connected to an output of the proportional pressure regulator, and a third connector configured to connect the air flow line to an air side of a diaphragm. Additionally, the control unit includes a controller programmed to control at least an opening and closing function of the proportional pressure regulator to attain a desired amount of air flow (volume per unit of time), positive or negative, within the air flow line.
